What happened to that guy being chased onto Grizzly River Run by 20 security CMs last night?

[hodad]

Just as my 7yo was exiting the ride this tall guy in a white t-shirt came loping toward the ride from Pixar Pier shouting at the top of his lungs. He entered the empty queue for Grizzly River Run, then about 20 cast members, mostly security guards and what looked like middle-managers, chased after him at the briskest walk possible. We left the park, and by the time we got to the Toy Story Lot I heard a brief comment coming out of a CM's walkie-talkie, but I didn't find out what happened. I assume he just got drunk and decided to ride the water ride, and his zealotry was a little too out-of-control for the zookeepers, but maybe something more malicious took place.

Any leads?
